Answer and Explanation:
The correct answer is D.
A work package is the lowest level of the WBS and provides a general description of the work to be completed by this work package. The WBS dictionary supplements the WBS by including more detailed information for each work package or other WBS components.
The WBS dictionary is an output of the Create WBS process and provides information such as the description of work, schedule milestones, quality requirements, and acceptance criteria for each work package.
Therefore, the acceptance criteria for the work package to be completed are described in the WBS dictionary.
Note, the wording of the question, "You are about to begin work on a work package...", suggests that project execution has already begun, thus implying the project management plan including all its components (such as the scope baseline that includes the WBS dictionary) has been finalized and approved.
Details for each option:
A. Incorrect. The project management plan is the document that describes how the project will be executed, monitored and controlled, and closed. While the information you seek is available in the project management plan (within the WBS dictionary which is part of the scope baseline which, in turn, is a component of the project management plan), there is another answer choice that more accurately addresses the question asked. When choosing between two seemingly correct answer choices, typically the more specific choice is the correct answer.
B. Incorrect. Activity attributes are the additional details associated with each schedule activity that can be included within the activity list. Activity attributes may include activity codes, predecessor activities, logical relationships, resource requirements, etc. However, the acceptance criteria for work packages are not among activity attributes.
C. Incorrect. As part of project planning, requirements are collected to develop the scope of the project. The requirements documentation describes how these individual requirements meet the business need for the project.
D. Correct. The WBS dictionary is a supporting document for the WBS and provides detailed information about each component in the WBS. Acceptance criteria for each of the work packages are included in the WBS dictionary, making this choice the best answer to the question asked.
